How to solve 3x+y=6 and y=-3 using substation method
mafiozo [28]

Answer:

x=3

Step-by-step explanation:

since they give you y this is a very simple problem

simply replace y with -3 and get

3x+(-3)=6

adding a negative number is the same as subtracting a positive number

3x-3=6

add 3 on both sides

3x=9

divide by 3 on both sides

x=3

Any ideas on how to find the value of 'x' on either 13 or 16? Anything helps!
Artemon [7]
(x+5)/4=1/2
first get rid of the fraction
multiply both sides by 4
x+5=2
subtract 5
x=-3

(2x+1)/(4x-1)=2/3
get rid of the fractions,
multiply both sdies by (4x-1)(3)
(2x+1)(3)=(2)(4x-1)
distribute
6x+3=8x-2
subtract 6x form both sdies
3=2x-2
add 2
5=2x
divide by 2
5/2=x

Please answer with steps shown. Thanks!

Answer: q = 40

Step-by-step explanation:

Given the quadratic formula as

x = [-b +/-√(b^2 -4ac)]/2a

b = -14

a = 1

c = q

Difference d between the two roots.

d = [-b + √(b^2 -4ac)]/2a - [-b -√(b^2 -4ac)]/2a

d = 2√(b^2 -4ac)/2a

d = √(b^2 -4ac)/a

And d = 6

Substituting the values of a,b and c. We have;

6 = √[(-14^2) - (4×1×q)]

Square both sides

6^2 = 196 - 4q

4q = 196 - 36

q = 160/4

q = 40

The equation becomes

x^2 - 14x + 40 = 0
